如何将Jersey与TomEE/openEJB集成

Question

我正在升级使用Jersey JAX-RS在Apache TomEE服务器上运行的代码.不幸的是,当我尝试将Jersey与TomEE一起使用时,它会抛出错误.

我正在使用eclipse并打开了JAX-RS项目方面.它指向泽西图书馆.我还将Jersey库移动到/ lib /目录中以尝试解决问题无济于事.服务器抛出以下错误:

有谁知道我怎么做这个工作？我也考虑使用tomEE + Jax-rs服务器,但似乎没有认识到杰克逊的注释.

编辑:我认为问题是openEJB CDI与泽西岛附带的CDI相冲突.我不知道如何解决这个问题.

Answer 1

复活!以防任何人仍然遇到这个问题.

我有一个运行在Tomcat peachy敏锐的Jersey应用程序,并且当我将它移动到TomEE时以这种方式爆炸.问题是TomEE已经有了自己的JAX-RS实现(在撰写本文时为tomee-jaxrs-1.5.0),这与jersey-bundle jar冲突.

我要摆脱这个问题所要做的就是删除jersey jars并注释掉web.xml中的servlet声明和映射

重新开始,中提琴!请记住,URL会略有不同.例如,在您可能拥有的默认平针织安装上http://localhost/rest/represent/me,当您将同一个应用程序移动到TomEE时,它将是http://localhost/represent/me

如果您正在使用像eclipse这样的IDE,可能会因为无法找到jar而咆哮,只需进入项目属性并将目标运行时设置为TomEE(您将不得不添加服务器实例),您应该是很高兴.

分享和享受.

Answer 2

我也遇到了这个问题,但是不幸的是grauwulf的答案对我不起作用.

在我的情况下,我有Tomee + 1.5.2,Jersey 1.1x,我也使用Spring 3.x.

修复实际上非常简单:

1. 找到Tomee system.properties文件({tomee}/conf/system.properties默认情况下).
2. 加 com.sun.jersey.server.impl.cdi.lookupExtensionInBeanManager=true

从那里开始,它对我有用.为了给予应有的信用,我在这篇博客文章中找到了它.

有趣的是,我也更喜欢避免{tomee}/lib使用war的依赖项来混乱我的文件夹,所以我还发现你可以通过修改{tomee}/conf/tomee.xml和添加以下节点(在<tomee />根节点内)轻松添加额外的lib :

<tomee>
  <Service
    id="extra-libs-enricher"
    class-name="org.apache.openejb.assembler.classic.enricher.AdditionalLibClassLoaderEnricherObserver">
      path = /path/to/your/libs
  </Service>
</tomee>

有了它Service,其名称是任意的,你不能传递path,默认为此时"additional-lib".默认情况下将使用传入的路径,但如果它不是目录,则它将回退到系统属性,该属性可以添加到system.properties文件中.系统属性是:openejb.enricher.additional-lib.

openejb.enricher.additional-lib=/fallback/path/to/your/libs

仅当传递到的路径Service或其默认值不起作用且仅当a Service放置在tomee.xml文件中时,才会检查此系统属性.它id是无关紧要的.
